Net margin still thin at 3.6%

• On a trailing 12 month view, STMicroelectronics generated US$13.1 billion of revenue and US$466 million of net income, which works out to a 3.6% net profit margin compared with 5.5% last year.
• Consensus narrative highlights long term margin improvement, but the current 3.6% trailing margin and a large one off loss of US$295 million show that profitability is still sensitive to shocks.
  • The margin gap versus last year plus the one off loss sit alongside forecasts for 11.9% yearly revenue growth and 37.7% yearly earnings growth, so the near term numbers are weaker than the growth story suggests.
  • Investors weighing that consensus view can use the Q2 2026 net income of US$222 million and basic EPS of US$0.25 as a reference point for how much improvement would be needed for margins to reach those forecast levels.

High 101.9x P/E sets a high bar

• The stock trades on a 101.9x P/E, which is above both the European semiconductor industry average of 55.1x and the peer average of 10.8x, despite trailing 12 month earnings of US$466 million on US$13.1 billion of revenue.
• Consensus narrative points to revenue growth of 11.9% per year and earnings growth of 37.7% per year, so the current 101.9x P/E and share price of €46.77 leave little room if that growth or margin recovery is slower than expected.
  • The analyst price target used here is €65.25, which sits above the current price, while the DCF fair value of €24.52 is considerably lower, so different approaches are giving very different signals on what the stock might be worth.
  • That spread between the 101.9x P/E and a DCF fair value below the current price encourages investors to check whether the forecast jump from a 3.6% trailing margin to higher future margins fits with their own expectations.

Earnings swing supports the bullish case

• Quarterly net income moved from a loss of US$97 million in Q2 2025 to a profit of US$222 million in Q2 2026, while basic EPS shifted from a loss of US$0.11 to US$0.25 over the same period.
• Bulls argue that growing automotive and Edge AI demand, together with capacity investments, could drive much stronger earnings, and the step up from US$37 million net income in Q1 2026 to US$222 million in Q2 2026 gives them some recent support to point to.
  • The bullish narrative in the data assumes revenue could grow 19.5% annually with margins rising from 1.2% to 23.3%, which is a big jump compared with the current 3.6% trailing margin and US$466 million of trailing earnings.
  • Those bullish assumptions also imply earnings in the billions of dollars by 2029, so readers can use the latest quarterly run rate and trailing 12 month totals to judge how ambitious that path looks.

On these numbers, the bullish camp is effectively asking whether STMicroelectronics can turn a recent US$222 million quarterly profit into multi billion dollar yearly earnings within a few years, which is a big stretch from the current base but not impossible if the business delivers on its pipeline and margin plans. 🐂 STMicroelectronics Bull Case
